我安装了PCS7V6.1，打开别人的PCS7程序（也是V6.1），只有站，没有程序，提示
the project contain objects of the software package 'HW-Update',which cannot be edited because the software package is not installed or exists in an earlier version.
帮助的文件：Help on Message 257:9
Description of Error:
The project may contain objects that can only be processed with an software package that is not installed or a newer version of the software package is required.
To Correct or Avoid Error:
Please install the required software package.
or
Make a copy of your project in the SIMATIC Manager [with File> Save As and the "With reorganization (slow)" option]. While the copy is being made, objects are deleted in the destination project if they belong to uninstalled software packages. The error message is then no longer displayed when you work with the copy of the project.
我打开别人的程序，也有硬件组态，但没有电源和CPU，请问是缺硬件更新吗？因为现场的电脑不能上网，有没有更新的文件，下载后在安装啊？http://www.ad.siemens.com.cn/download/DocList.aspx?TypeId=5&CatFirst=1&CatSecond=0&CatThird=0
这个地址的下载后安装还是不行啊，请那位专家帮一下忙啊？
最佳答案
有可能别人的程序使用了当前版本所不支持的硬件，你需要更新硬件。
PCS7最好不要通过Option>Install HW Updates的方式进行硬件更新，而需要下载专门的硬件升级包进行升级。
